We proposed an ultrafast optical arbitrary waveform synthesizer and analyzer in the femtosecond and
picosecond time regions. Ultrafast waveforms were generated by manipulating the amplitude and the
phase of a 200-GHz optical frequency comb (OFC) using a customized colorless optical synthesizer.
The synthesized waveform was then analyzed on the frequency axis using a custom heterodyne-detection
technique based on dual-heterodyne mixing. With our proposed system, we generated femtosecond
pulses and synthesized composite amplitude-shift and phase-shift keying signals of 22.4-Tbit/s with
112-bit packets in data processing.
